(provided). Tighten the bolts until snug. Do not over-tighten. Since the bolts are stainless steel, it is
recommended to lubricate the bolts before installation to prevent them from sticking or seizing. A dry
“Moly” type lubricant is recommended. Also, make sure that the serial number on the top half of the
Measuring Head matches the serial number of the lower half and that the halves go together squarely
and evenly without forcing, twisting or cocking. If for some reason the head halves do not press tightly
together, do not try to force the heads closer together as it might lead to damage. Check for obstacles
preventing the head from mating properly. Mounting the Measuring Head backward will not damage
the equipment, however the meter will read zero. After final positioning of the head, secure the
mounting feet permanently to the floor or platform.
4.4 INSTALLATION CONSIDERATIONS
In general, the Measuring Head can be installed vertically, horizontally, or in any intermediate
orientation. The Measuring Head is equipped with several mounting holes that can be used to
bolt the Measuring Head to a wall or support frame around the bus. Alternatively, optional
mounting feet can be purchased that can simplify mounting the Measuring Head to a platform
or wall. Also available, are bus bar mounting kits that allow the LKP-15 or LKP-30 Measuring
Heads to be mounted directly onto a bus bar. These kits eliminate the need to assemble any
additional mounting platforms or brackets. The prime considerations in all mounting cases are
as follows:
Read and follow the following considerations before mounting the Measuring Head.
A.
Choose a mounting location where the ambient air temperature does not exceed 55°C.
The standard Measuring Head is designed for indoor use only and should be kept away
from high heat and corrosive atmospheres. Protect the Measuring Head from direct
sunlight which causes the Measuring Head temperature to rise, thus limiting the upper
operating range in some applications. If the Measuring Head is to be installed in a
harsh environment, please discuss protective measures with the factory.
B.
The Measuring Head must be protected from water. The LKP and LKB sensor
Measuring Head designs rated 15 kA and higher are tested to meet IP 64 when
manufactured, indicating protection from splashing water from any direction. However,
this rating is not a blanket approval for simply installing it outdoors without additional
water protection. The Measuring Heads are splash proof but are not waterproof.
Classification IP 64 acknowledges that some water may penetrate the seal. Water that
invades the sensor is likely to cause long-term destruction. Consequently, it is
necessary to provide some rain and snow protective covering if the equipment is to be
mounted outdoors or in the vicinity of a sprinkler system.
C.
To minimize distortion of the magnetic field as seen by the Measuring Head, temporary
and final support members should be nonmagnetic (for example, aluminum beams,
struts or stranded cables, or wood, fiberglass, or Phenolic where appropriate). It is
recommended to keep large structural magnetic materials at least 2 meters distant from
the Measuring Head. For additional details refer to Technical bulletin No. 987 titled
“Ferromagnetic Materials Near LKP or LKB Current Sensors.”
D.
The Measuring Head is designed to be supported from the bottom. The top half should
be attached to an anti-tipping brace.
Never suspend the Measuring Head by the top
half alone
. If the heads are to be mounted in a position other than vertical, each half of
the head should be independently supported. Additional drilling of the Measuring Head
is NOT authorized, as damage may result.
